The president's son was convicted of unlawfully purchasing a firearm.
President Joe Biden's son Hunter Biden has been found guilty on three felony counts related to his purchase of a firearm in 2018 while allegedly addicted to drugs.
The younger Biden, who pleaded not guilty last October after being indicted by special counsel David Weiss, denied the charges. The son of a sitting president had never before faced a criminal trial.
The trial came on the heels of former President Donald Trump's conviction on felony charges related to a hush money payment made to boost his electoral prospects in the 2016 presidential election.
Prosecutors have rested their case against President Joe Biden's son Hunter Biden.
The defense is scheduled to present its case next.
Defense attorneys have said they could possibly wrap up their case by Monday, in which case jurors could begin deliberations as soon as Tuesday or Wednesday.
DEA special agent Joshua Romig took the stand to testify as an expert in the "coded language" used in drug trafficking.
He analyzed the language used in some of Hunter Biden's text messages, some of which appeared to be drug transactions.
First lady Jill Biden, back in the courtroom this morning, looked on as Romig testified.
Special counsel David Weiss, who brought the case against Hunter Biden, is also in court today.
Chemist Jason Brewer, testifying as an expert witness for the prosecution, told the jury that a brown leather pouch that contained Hunter Biden's gun at the time the weapon was retrieved by authorities tested positive for cocaine.
Brewer said there were "minimal amounts of white powder" on two locations on the pouch, which he combined and tested.
On cross-examination, Hunter Biden's attorney sought to raise doubts about how that white powder got there and who put it there -- emphasizing it could have been old, dating back to before Hunter Biden purchased the gun.
"You can't date when it got there?" defense attorney David Kolansky asked.
"I cannot," Brewer said.
Kolansky also emphasized that five years went by from the time the pouch was collected in October 2018 to when it was tested in October 2023 -- after the indictment in this case was already filed.
He emphasized the importance of the "chain of command," which Brewer conceded was "very important."
Earlier, Hunter Biden's former girlfriend Hallie Biden testified that she put the gun in the pouch, which she found in Hunter Biden's vehicle, after she discovered the weapon in the vehicle and before she disposed of it in a trash container.
Proceedings resumed this morning with the government calling FBI chemist Dr. Jason Brewer to the stand.
Brewer is testifying as an expert witness.
Prosecutors said they would then call a DEA officer as their final witness.
